To all whom it may concern:

Be it known that I, ALFRED MORELL, a citizen of the United States,residing at Worcester, in the county of Worcester and State ofMassachusetts have invented certain new and useful Improvements inWeft-Replenishing Looms, of which the following is a specification.

My invention relates to weft replenishing looms, and to the fillingtransferring mechanism thereof, and more particularly relates to. thetrip or dagger carriedon the transferrer arm of the transferringmechanism.

The object of my invention is to improve upon the ordinary constructionof the trip or dagger carried on, or connected with the 1 transferrerarm, and which is adapted, on the practical exhaustion of filling, to bemoved into the path of and be engaged by the bunter on the lay, on theforward movement thereof, to cause the movement of the transferrer' arm,to engage and trans er a fresh bobbin from the magazine into the activeshuttle, to take the place of the practically exhausted bobbin in saidshuttle.

In the ordinary construction of the trip or dagger connected with thetransferrerarm, there is no yielding or give-way movement of saiddagger, independent of the transferrer arm, when said dagger is moved'into osition' to be engaged by the bunter on. the Forward movement ofthe lay, and if for any reason a bobbin which is to be dischar d fromthe magazine and pushed into the s 'uttle by the transferrer arm, is notin proper position to enter the shuttle and push out the old bobbintherein, but is prevented from so doing, then the transferrer arm. beingforced down by the engagement of the bunter with the dagger or triponthe transferrer arm, on the for-ward movement of the lay, some part ofthe mechanism must give way or break- In my improvements, I provideayielding or give-way device connected with the trip or dagger, which isattached to the transferrer arm, and which in the normal operation ofthe loom will remain in apredetermined fixed position to receive theimpact of the bunter on the forward movement of the lay, and cause themovement of the transferrer arm in the usual way, to transfer a bobbinfrom the magazine into a shuttle, but in case the bobbin is preventedfrom entering the shuttle when the transferrer arm is operated,

or there is any obstruction to the down-ward movement of the transferrerarm, then said device will yield or give way on the engagement of thebunter therewith, without cans-- ing the complete movement of. thetransferrer arm, and thus preventing anybreaking of the parts.

' I have only shown inthe drawing a' de' tached portion of the weftreplenishing mech:

anismof a weft replenishing l'oorn', having a stationarymagazine,.withmy'improv'ements combined therewith, sufficient to enablethose skilled in' the art to understandthe construction and operationthereof;

' Referring to the drawing:Figure l is anend view of a detached portionof a stationary magazine, and a weft replen shing or transferringmechanism, and a sectional View of the lay-beam in its forward position,and of a shuttle on the lay-beam, showing the several: parts in theirrelative positions, after the transfer of a bobbinfrom the magazine hasbeen completed. Fig. 2 corresponds to- Fig;

Fig. 3 is, on anenlarged scale, an inner end view of the trip or-d'agger shown in- Fig.1 detached, looking in the direction of arrow a, same figure. Fig. 4- isa viewof the parts shown" in Fig. 3, looking in the direction of arrow5', same figure. Fig. 5-is 'asection', on line 5*, 5, Fig. 3, looking inthe direction of arrow 6-, same figure, and, Fig; 6 shows some of thepartsshown at the left in Fig.2, in another position.

In the accompanying drawing, 1 is 8; (fe tached portion of the loomframe or end, 2 is a detac on, which is-ad'apted to'support a stationarymagazine or bobbin holder 3,.on1y the lower part of which is shown. Themagazine 3- is in this instance of the stationary type, having fourvertically extending guidewa-ys or compartments for four sets of bobbins4 and means for holding the lowest bobbin in each guideway orcompartment in position'ready to drop down by gravity into a position atthe lower discharging end of the magazine,

where it will be engaged bythe transferrer' arm, and moved through theopening at the" ed portion of a stand secured there-v 6, and 7 is aportion of the shuttle box on the lay-beam. 8 is a shuttle, having abobbin 4 therein. On the front of the lay beam 5 is carried a hunter 9.The transferrer arm 10 is pivotally mounted on a stud 1 1, and has anengaging end 10 thereon, which engages a bobbin 4, and a downwardlyextendingarm 10 thereon carrying a stud or pin 12, on which is pivotallymounted a trip or dagger 13. A spring 1 1 acts to raise and hold thetransferrer arm 10 in its raised position, and a spring 15 acts to movethe trip or dagger 13 into its raised position, and into the path of thebunter 9, when the arm 13 thereon is released by the hook connector 16,adjustably connected to the lower end of a lever or arm 17, the hub ofwhich. not shown, is pivotally mounted on the stud ll' and has anextension. thereon which is connected through intermediate mechanismwith the filling detector or indicating mechanism, not shown, at the oposite end of the loom, in the usual and wel known way. All of the abovementioned parts, except the trip or dagger 13, may be ofthe usual andwell.

looms of the class referred to.

I will now describe my improvements in the tri or dagger 13 which isprovided with a yiel ing or give-way device td'be'engaged by. thehunter, and which will on the extreme forward movement ofnthe lay, yieldor give Way, when engaged by the hunter, allowing the trip or dagger 13to move down to its-lowered position, out of the path of the hunter, andpermit the transferrer arm 10 to remain stationary, without completinits known construction in weftreplenishing downward movement, in casethe bobbin to be transferred is not in proper position to enter theshuttle, or there is any obstruction to the downward movement of thetransferrer arm 10.

The trip or dagger .13 com rises as a part thereof, in this instance, ap ate or bar 13, having a beveled inner end 13", and a beveled shapedextension 13 thereon, see Fig. 3,.to extend into a correspondingrecessed portion in the trip or dagger 13, and be ad'- justed therein inthe direction of the length of the plate 13, by a set screw or bolt 18,see Fig. 5, which turnsin a threaded hole in the trip or dag er 13.! Theplate or bar 13 is secured in a justed position by a bolt 19, see Fig.3. The late or bar 13 has thereon a boss or roun ed portion 13, see-Fig. 4, to receive a longitudinally moving pin 20, which has itsengaging end 20' beveled, or of wedge shape, and has the reduced portion20 to receive a helically coiled expansion spring 21, which extendswithin the boss 13, and bears at one end against the end thereof, andat-its other end against the enlarged end of the in 20, see Fig. 5. nut22 on the screw t eaded end of the pin 20 is used to adjust the pin 20within the boss13 to regulate the tension of the spring 21, and a secondnut 23 acts as a lock nut.

The inner beveled end of the plate or bar 13, with the beveled head 20of the spring actuated pin 20, forms a beveled recess to receive thebeveled end of the hunter 9, as shown in Fig. 1, and the beveledengaging end of the hunter 9 is of such a shape, relative to the beveledrecess formed by the beveled end of the plate 13 and the beveled end ofthe pin 20, that in the normal operationof the loom and the transferrermechanism, the hunter, as the lay moves forward will engage and remainin the beveled recess at the inner end of the dagger or trip 13, andmove backwardly the transferrer arm 10, to engage and transfer a bobbinfrom the magazine into a shuttle.

The pivotal support or fulcrum of the dagger, and the direction ofmovement of the hunter 9 are relatively such, that the direction ofmovement of the hunter is in a line which will pass above the pivot ofthe hunter, so that the dagger cannot move downon its pivot support, andconsequently the trans-,

errer arm must move down as the dagger moves backwardly. But if for anyreason the transferrer arm 10 is prevented from completing its downwardmovement, and

consegu'ently the dagger or trip cannot be move backward to its extremeposition, then the shape of the beveled engaging end of the hunter 9,relative to the inner end of the dagger 13, is such, that the hunterwill push back the pin 20 enough to let the hunter pass by said pin, andallow the dagger 13 to drop to its lowered position, as shown in Fig. 6.i

The operation of my improved trip or dagger 13 will be readilyunderstood by those skilled in the art.

The spring 21 is of sufficient strength to hold the pin 20 on the dagger13 in its out-' Ward position in the normal operation of the loom, withits beveled head 20 in substantial alinement with the beveled end 13 ofthe plate or bar 13, to receive the impact of the dagger 13 on theforward movement of the lay, as shown in Fig. 1, and cause,

through the movement of the dagger 13, the

downward movement of the transferrer arm 10, to transfer a bobbinfromthe magazine into the, shuttle in the usual Way; but

in case a bobbin is not in proper position to be transferred from themagazine, so that the transferrer arm cannot complete' its -movement,then the engagement of the hunter 9 with the dagger 13, on the forwardmovement of the lay, will as the, lay approaches its extreme forwardposition, move outwardly the s ring actuated pin '20, which forms a yiedin or give way device for the dagger, and a ow the hunter 9 to pass bythe dagger 13, as shown in 2, and allow the dagger 13 to drop down, asshown in Fig. 6, and leave the transferrer It will be understood thatthe details of construction of my improvements may be varied if desired,and they may be adaptedto be applied to and used with the transferrer'arm of magazines of different construction, either stationary ormovable.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. In a. transferrer mechanism of a weftreplenishing loom, the combination with a bunter on the lay and thetransferrer arm, of a trip or dagger connected with the transferrer arm,and having a yielding or giveway part to be engaged and moved by saidbunter, on the forward movement' of the lay, in case of obstruction tothe movement of the transfrrer arm.

2. In a transferrer mechanism of a weft replenishing loom, thecombination with a bunter on the lay, and the transferrer arm,

' of a trip or dagger connected with the transferrer arm and having ayielding or givewaypart to be engaged and moved by said bunter on theforward movement of the lay,

in case of obstruction to the movement of the transferrer arm.

3. In a transferrer mecha'nlsm of a weft replenishing loom, thecombination with a bunter on the lay, and the transferrer arm,

of a trip or dagger connected with the transferrer arm and having ayielding or give- Way part, said yielding part consisting of a springactuated longitudinally moving pin, having a beveled end to be engagedby the bunter and moved outwardly.

4. In a transferrer' mechanism of a weft replenishing loom, thecombination with a bunter on the lay, and the transferrer arm, of a tripor dagger connected with the transferrer arm and having a yielding orgive way part, said yielding part consisting of a spring actuatedlongitudinally moving pin, having a beveled end to be engaged by thebunter and moved outwardly, said pin having a support adapted to beadjusted on the dagger, to vary the position of the engaging end of thepin relatively to the engaging end of the dagger.
